How to recalculate position, when copy template

I want to ask how to recalculate line number position and other data when I copy template from another xml file if satisfy condition that code should be the same like in lookup.xml.

My programs look like that:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">
    <xsl:output omit-xml-declaration="yes" indent="yes"/>   
    <xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template> 
    <xsl:template match="Line-Item[code = document('lookup.xml')/*/*/code]" />
    <xsl:template match="Line[not(Line-Item/code[not(. = document('lookup.xml')/*/*/code ) ] )]"/>  
</xsl:stylesheet>

xml file:

<document>
    <header>
        <remarks>test</remarks>
    </header>
    <Line>
        <Line-Item>
            <lineNumb>1</lineNumb>
            <code>123</code>
            <amount>4</amount>
        </Line-Item>
        <Line-Item>
            <lineNumb>2</lineNumb>
            <code>444</code>
            <amount>2</amount>
        </Line-Item>
        <Line-Item>
            <lineNumb>3</lineNumb>
            <code>321</code>
            <amount>1</amount>
        </Line-Item>
    </Line>
    <summary>
        <total-line>3</total-line>
        <total-amount>7</total-amount>
    </summary>
</document>

Lookup.xml file:

<lookup>
    <开发者_如何学JAVA;Codes>
        <code>123</code>
    </Codes>
</lookup>

I need recalculate lineNumb in Line-Item, And summary there is total-line and total-amount.

Correct result:

<document>
    <header>
        <remarks>test</remarks>
    </header>
    <Line>
        <Line-Item>
            <lineNumb>1</lineNumb>
            <code>444</code>
            <amount>2</amount>
        </Line-Item>
        <Line-Item>
            <lineNumb>2</lineNumb>
            <code>321</code>
            <amount>1</amount>
        </Line-Item>
    </Line>
    <summary>
        <total-line>2</total-line>
        <total-amount>3</total-amount>
    </summary>
</document>

Your work is almost done. You need only XPath count() and sum(). To recalculate the lineNumb, I've counted all previous sibling elements but the ones matching the lookup code.

I think this should work fine on the base of your assumptions.

    <xsl:template match="Line-Item[code = document('lookup.xml')/*/*/code]|summary" />
